Basically i want to make a R15 Guns with R6 arms when you go in first person view but i dont want the arms to be seen by other players. How would i do this?
To set the R6 arm cframe, just use CFrame.new(Shoulder, Hand) Just make the arms on the client side. If your game isn't filtering enabled, then I don't see why you're trying to make a game.
If the fake R6 arms are descendants of the character, then you'll have to set the local transparency and transparency to 0. Not sure if you have to loop this, for my fake arms I currently am but now that I think about it, you probably don't have to.
